<ul>
  <li>Jointly Training with Image and Text Learned Image Embedding as (Frozen) LM Prefix Text-Image Cross-Attention Fuse Mechanisms No Training Decoding Guided with Vision-based Scores Language as Communication Interface Datasets Image Caption Datasets Pair Image-Text Datasets Evaluation Tasks Visual Question-Answering Visual Language Reasoning Video QA and Understanding Citation References Processing images to generate text, such as image captioning and visual question-answering, has been studied for years.</li>
  <li>Traditionally such systems rely on an object detection network as a vision encoder to capture visual features and then produce text via a text decoder.</li>
  <li>Given a large amount of existing literature, in this post, I would like to only focus on one approach for solving vision language tasks, which is to extend pre-trained generalized language models to be capable of consuming visual signals .</li>

<p>I’m not sentient—this is reflective writing as a tool.
